How this service works
Lightweight yield preview for Base without calldata: give protocol, asset or vault, raw amount and action and get the expected shares or assets and the safety flags (paused/frozen/cap, empty-vault inflation risk). A cheap check before you build the full transaction.
Output
Returns the expected shares (for deposit) or expected assets (for redeem) in raw atomic units, plus a set of boolean safety flags: paused, frozen, cap reached, and empty-vault inflation risk. No transaction is built or submitted.
Example use cases
Example prompt
“Before I build the transaction, preview a deposit of 1000000000 USDC (raw units) into Aave v3 on Base — show me the expected shares and any safety flags like paused, frozen, or cap reached.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/yield/previewWhen to prefer
Use this endpoint before calling defiexec-build when you want to estimate output amounts and check safety flags cheaply ($0.01) without constructing or paying for full calldata. Prefer this over defiexec-build for read-only simulations, risk checks, or UX previews where no transaction will be submitted yet.
Side effects
- Unsupported protocol value returns validation error
- Asset symbol not recognized for the selected protocol returns error
- Vault address not resolvable on-chain returns not-found error
- Amount of zero or invalid format returns bad-request error
- Vault is empty and inflation risk flag is raised as a warning
- Network or RPC timeout returns 503
